为保持较低的矿石开采成本,保证矿山经济效益,南芬露天矿提出对290平硐上方爆区采用减震爆破方法,以延长290平硐的使用寿命。本文主要针对如何进行爆破设计,以减小爆破震动.并结合邻近平硐的几个开采爆区实例.阐述新爆破方法的起爆网路和装药结构的设计研究及爆破效果.为以后类似爆区的设计提供参考及理论依据。
In order to keep the cost of ore mining lower and ensure the economic benefits of the mine, Nanfen Open-pit Mine proposed to adopt the method of blasting blasting to the blasting area above the 290 adit to prolong the service life of 290 adit. This paper mainly focuses on how to carry out the blasting design to reduce the blasting vibration, and combines with several excavation blasting examples of the adjacent adit.Describes the design and blasting effect of the blasting network and charge structure of the new blasting method, District design provides a reference and theoretical basis.
